To explore predictors of breastfeeding behavior and seek to replicate prior findings using a recent nationally representative United States (US) sample, which has not been done previously.
Secondary data analysis using the National Survey of Children's Health 2011 to 2012.
Households in the 50 US states, the District of Columbia, and the US Virgin Islands.
Caregivers with a child between 6 months and 6 years of age (n = 26 552).
Caregiver-reported child breastfeeding behavior, child birth weight, child/maternal/family demographics, maternal physical and mental health, and household tobacco exposure.
A multinomial logistic regression explored whether child, maternal, and family characteristics predicted exclusive breastfeeding for 6 months or breastfeeding for a suboptimal duration.
Approximately 79% and 17% of the sample-initiated breastfeeding and exclusively breastfed for 6 months, respectively. Child ethnicity/race, maternal education, household tobacco exposure, family composition, and family income predicted odds of both exclusive breastfeeding for 6 months and breastfeeding for a suboptimal duration or not exclusively. Normal or high child birth weight and better maternal physical health predicted greater odds of exclusive breastfeeding for 6 months.
Rates of exclusive breastfeeding for 6 months remain low in the United States. Single-parent and step-families, lower income families, non-Hispanic black children, children with exposure to tobacco, and children of mothers with lower education are at greatest risk.
探索母乳喂养行为的预测因素，并使用最近具有全国代表性的美国（US）样本复制先前的发现，此前尚未进行过此类研究。
使用 2011 年至 2012 年的全国儿童健康调查进行二次数据分析。
美国 50 个州、哥伦比亚特区和美属维尔京群岛的家庭。
有 6 个月至 6 岁儿童的照顾者（n = 26552）。
照顾者报告的儿童母乳喂养行为、儿童出生体重、儿童/母亲/家庭人口统计学、母亲身体和心理健康以及家庭烟草暴露情况。
多项逻辑回归探讨了儿童、母亲和家庭特征是否预测了 6 个月的纯母乳喂养或母乳喂养时间不足。
大约 79%和 17%的样本分别开始母乳喂养和 6 个月纯母乳喂养。儿童种族/民族、母亲教育、家庭烟草暴露、家庭构成和家庭收入预测了 6 个月的纯母乳喂养和母乳喂养时间不足或不进行纯母乳喂养的可能性。正常或高出生体重和更好的母亲身体健康状况预测了 6 个月的纯母乳喂养几率更高。
在美国，6 个月的纯母乳喂养率仍然很低。单亲家庭和再婚家庭、低收入家庭、非西班牙裔黑人儿童、接触烟草的儿童以及母亲教育程度较低的儿童风险最大。
